The two were inside Greystone Manor, a West Hollywood club at the same time, but they left the club separately.A few sources told the website that Rihanna and Chris did not spent time together inside the club. But was it just a coincidence?We recall you these two used to date back in 2008 and 2009 until Chris hit Rihanna. He was then forbidden to get close to the singer, but the protective order was lifted a year ago.
